Avaliação estrutural do pavimento com utilização da viga Benkelman tradicional. Estudo de caso: via interna do Campus Paulo IV - UEMA

Abstract

It is known that only the determination of maximum recoverable deflections is not sufficient for a more accurate structural evaluation of a pavement, so it is necessary to know the shape of the deformation basins, where more information about the pavement structure is available. Thus, the orderly distribution of analysis sections along a floor segment will provide the structural conditions of the section in that period, serving as a comparison for other surveys conducted in different periods. This study consists of an investigation of the newly recaptured roads of the Campus Paulo VI of the State University of Maranhão (UEMA), where functional and deflectometric data were collected, based on the current norms of the National Department of Transportation Infrastructure (DNIT). It will be focused on the determination of the recoverable deflections and the design of the deformation basin through the traditional Benkelman beam. In the analysis of the results obtained, the equipment provided approximate data for use in paving projects, that is, they can be used in the measurements of the maximum deflections and be used in any of the official methods of current DNIT projects. In a simplified structural analysis, the structure of the pavement evaluated was shown to be 50% compromised, including segments requiring reinforcement or reconstruction probably related to the underlying layers
